T 0 all whom-it may concern:

Be it known that 1, JOHN BOWEY, Jr., of the city of London, in the Province of. Ontario, Canada, have invented certain new and useful Improvements in Water-Purifiers, of which the following is a specification.

My object is to devise simple and effective apparatus for measuring the water and chemical solution to be added thereto, and forthoroughly agitating the latter.

Figure 1 is a side elevation of my improved water purifier partly broken away to expose the internal construction. Fig. 2 is a plan view of the same. Fig. 3 is a sectional detail of the lock and release devices of the receivers. Fig. 4 is a plan view of the device for opening the valve of the chemical solution valve chamber. Fig. 5 is an end elevation of the same. Fig. 6 is a sectional detail of part of a float valve supplying solution to the valve chamber. Fig. 7 shows an end and side elevation of one of the connecting disks of the horizontal shafts conveying motion to the agitator. Fig. 8 is a vertical sectional detail showing an alternative form of the chemical solution measuring apparatus.- Fig. 9 is a plan view of the same.

In the drawings like letters of reference indicate corresponding parts in the different figures.

1 is a pipe supplying water to the distributing reservoir 2. This reservoir is provided with two openings in its bottom, controlled by the hinged valve 3. These openings are located respectively over the two receivers 8, which are connected by the sprocket chain 5 which passes over the sprocket wheel 6, which is secured to the horizontally j ournaled shaft 20. These receivers are arranged to work between suitably shaped vertical guides 4. The receivers thus balance one another, and each is capable of vertical movement, one rising while the other is falling. I automatically impart this rising and falling movement by the constructions which I will now describe;

It will be seen that each receiver is provided with a projection 11 adapted to engage and lift one of the valves 3. Each receiver is also provided in its bottom with an opening controlled by the hinged valve 9. Be-

' low these valves, in the trough 47 are located the pins 48, so placed as to contact with and raise the valves when the receivers reach their lowest position. From this construction it follows that when a receiver is in its highest position it will lift one of the valves 3 and water from the reservoir at once flows into the receiver, and continues to flow as long as the valve is held open. While one receiver is filling the other is emptying owing to the valve 9 in its bottom being lifted by contact with one of the pins 48. It is evident, however, in order that the uppermost receptacle be completely filled, that it is necessary to provide means to hold it in its raised position until it is full, otherwise it would commence to move downward the instant it overbalanced the emptying receiver. For this purpose I provide the catch or detent shown particularly in Fig. 3 for each receiver.

Each catch 17 is pivoted on the frame of the apparatus, and is normally pressed by the spring 18 towards a position 1n which it will engage beneath the lug 19, secured to the side of the receiver 8. These catches 17 are located, as shown, to engage one of the lugs 19 when a receiver is in its highest position. In order to release the catches when the receivers are full I provide each receiver with a float 15, which is secured to the crank lever 14 pivoted within the receiver, and having its end adapted to engage the catch, as shown in Fig. 3.

When the water in the receiver reaches a redetermined level the float is lifted and reeases the catch allowing the receiver to descend. On reachin the bottom the receiver is emptied, as already described, and this intermittent motion will continue as long as water is supplied to the reservoir. Measured quantities of water are then intermittently delivered to the trough 47, and at the same time an intermittent rotary motion in opposite directions is imparted to the shaft 20. A second shaft 20 a is journaled in line with the shaft 20, and is driven therefrom by a clutch, which will be hereinafter described. This shaft 20 is used to drive an agitator 27 located within the chemical solution tank 26. This agitator comprises a series of arms suitably secured to a vertically journaled shaft 25, driven by bevel gearing 23, 24 from the shaft 20. The movement of the receivers is thus utilized to thoroughly agitate the chemical .solution. I

The clutch between the shafts 20 and 20 hereinbefore referred to, comprises two disks 22 connected to one of the shafts. Each disk is provided with one or more lugs 21 which lie in the paths of those on the other. Thus when the shaft stops revolving the shaft 20 driven by the momentum of the agitator, is free to revolve until the lugs 21 engage on opposite sides to their original engagement. By this arrangement I avoid the ars which would otherwise result from the sudden stops of the shaft 20. So too, the shaft on the commencement of its reverse movement in either direction is enabled to acquire a certain momentum before the lugs rengage and the work of driving the agitator is placed upon it.

The chemical solution may be measured in various ways, a preferable form being shown particularly in Figs. 1, 4 and 5. A valve chamber is provided below the level of the solution holder 27. An outlet pipe a leads from the solution holder to a point above the valve chamber, and its opening is controlled by a float valve 29, of which the float 36 is located within the valve chamber 30.. This float valve will close the outlet pipe as soon as the solution in the valve chamber reaches a redetermined height. A valve 38 is provi ed in the bottom of this valve chamber,

and means hereinafter described provided whereby this valve is lifted each time a receiver reaches its lowest position. The contents of the valve chamber then flow off through the conduit 49 into the trough 47. As the float valve insures a constant head in the valve chamber each time the valve therein is opened the rate of flow from the valve chamber will always be the same no matter what the height of the fluid may be in the solution holder 26. Thus a proper proportion of chemical solution, relative to the contents of the receivers, will in each case be allowed to pass through the conduit to mingle with the water in the trough 47.

In Figs. 4 and 5 I show particularly the means for operating the valve 38. A con necting rod 44 is pivotally connected with the valve 38, and also with an arm 43 secured to the shaft 39. This shaft is suitably j ournaled, and to a suitable part is secured a flat spring 46 which engages an elliptical cam secured to the shaft, and so placed that the pressure of the spring tends to maintain the shaft in the position it assumes when the valve is closed. Arms 41 are hinged on the bar 40 secured to the shaft 39. A rule joint, or an equivalent construction, is preferred which will make the arms 41 rigid relative to downward pressure, and enable them to yield to upward pressure, as indicated in dotted lines in Fig. 5. The shaft 39, it will be seen, is located between the receivers 8, and the arms 41 are arranged in the path of the lugs 42 secured to the receivers 8. From this construction it follows that each receiver as it descends will cause its lug 42 to strike one of the arms 41, thus rocking the shaft and opening the valve 38. The contents of the valve chamber immediately flow out, and as I the lug 42 passes the arm 41 the valve is again closed, as already described, by the action of the spring 46. On its upward movement the receiver simply rocks the arm 41 on its hinge and passes'by without affectingthe shaft 39.

The solution in the measuring chamber is preferably agitated. For this purpose I provide an agitator 37, comprising arms secured to'a vertically ournaled shaft 32, preferably journaled in arms 31 extending from the solution tank 26. A sprocket wheel on the upper end .of the shaft is driven by means of a sprocket chain 34 from the sprocket wheel 35 on the shaft 25. tioned that for the purpose of securing a more efficient agitation in the tank 26, stationary arms 28 are secured to the inner side of the tank between the arms 27 (see Fig. 1).

As an alternative to the chemical solution measuring device I illustrate the forms shown in Figs. 8 and 9. Two vertically movable rods are provided passing through guides 58, which may be secured to any suitable support. ,On each is pivoted a bucket 51,which is normally pressed towards the wall of the solution holder by means of a bent spring 52. To each rod is secured a cord or chain 54 which passes over a guide pulley 55, and may be secured to one of the receivers. Thus each rod may be lifted and allowed to-fall according to the movements of the receiver to which it is connected. When the rod is in its lowered position the bucket 51 is filled. When the rod is lifted the spring 52 will tip the bucket over on to the shelf 56, as shown, causing its contents to be emptied into the conduit 57, which will be led to a convenient point of discharge. A small friction roller 58 is preferably connected to the front of each bucket to reduce the friction between the bucket and the wall of the holder. These buckets, as described, will operate in unison with the receivers, and will accurately measure a sufficient quantity of chemical solution corresponding with the water measured by the receivers.
